UNITED STATES PATENT OFFIon FRANCIS O. CLARK, OF DES MOINES, IOWA.

IM PROVEM ENT IN CARPET-FASTENERS.

Specification forming part of Letters Patent No. 200,172, dated February12, 1878; application iled J une 29, 1876.

To all whom it may concern:

Be it known that I, FRANCIS O. CLARK, of Des Moines, in the vcounty ofPolk and State ofl Iowa, have invented an Improved Carpet- Fastener, ofwhich the following is a specilication:

The object of my invention is to secure a carpet to a floor by means ofpermanentlyiiXed carpet-nails and adjustable and movable carpet-strips,in such a manner that the edge of the carpet andl the nails holding itwill be concealed and the corners lled, and the room ornamented by asolid molding, that can be readily put down and secured and as readilyreleased and removed to lift the carpet without the aid of any tools.

It consists in a novel manner of forming, arranging, and combining awooden carpetstrip, a sheet-metal strip, and a carpet-strip keeper witha series of doubled-pointed carpettacks, all as hereinafter more fullyset. forth and claimed.

Figure 1 of my drawings is a perspective view, illustrating theconstruction, application, and combination of the several parts composing my invention.

A represents the oor of a4 room; B, the base-board; C, the carpetcovering the door. a a is a row of double-pointed tacks, permanently Xedin the ioor by means of a suitable setting device, in a straight line,about half an inch distant from the base-board B.

bis a wooden carpet-strip, having a longitudinal groove in its underside, corresponding with the row of tacks a, which enter its groove c.

d is a sheet-metal carpet-strip, corresponding in size and shape withthe wooden strip b, which it covers. ff are lianges on the longitudinaledges of the sheet-metal strip d, designed to lap over the corners ofthe wooden Strip b.

g is a metal keeper, conforming in size and shape with the metal stripd, over which it is placed to lock the complete carpetstrip into thecorner. It has a straight head, h, at its top end, and an open eye orslot, d, in the top of the head.

k is an elbow-form screw or tnrn-button, that enters the base-board B,and serves to clasp the head of the keeper g rigidly to the surface ofthe base-board, and to thereby retain the keeper in proper position, asrequired, to hold down and lock the carpet-strip in its place, to

cover the nails and the edges of the carpet, and to prevent the carpetfrom slipping from the nails.

Fig. 2 is a section of my wooden strip b, having the groove c in itsunder side. They may be formed in any suitable manner, and vary inlength and thickness, as desired. 'Ifhe groove c adapts them to fit uponthe row of nails a in such a manner that the strip can be readily putdown and taken up at pleasure.

Fig. 3 is a section of my sheet-metal strip d, having the flanges ff.These longitudinal flanges adapt it to be filled with the correspondingsections of wooden strips b, which readily slide in and out endwise.

Fig. 4 is a perspective view of my metal carpet-strip keeper g. It maybe stamped from sheet metal by means of dies, or cast in molds.

Fig. 5 is a perspective view of my doublepointed carpet-tack.

From the detailed descriptions and functions of the various partscomposing one of the complete carpet-fasteners, and the carpettackswhich I use in combination with my carpetfastenin g devices, the mannerof its use is obvious, and its novelty and advantages are apparent as asimple, complete, and convenient means of fastening carpets in rooms,halls, and 011 stairs.

I am aware that a stair-rod fastener having a shoulder and an eyesimilar to mine has been used; but I consider that my form ofkeeper,.adapting it to fit over and clamp a carpet-strip in the mannerdescribed, is a new and valuable improvement.

I claiml. The wooden carpet-strip b, having a longitudinal groove, c, inits under side and near its central line, adapted to receive and engagea row. of pointed carpet-holding nails, a, fixed in the ioor, in themanner shown and described.

2. The series of fixed carpet-nails a., the

combined wood and metal carpet-strip b d,

having the groove c, the keeper g, .and a revolving screw, k, arrangedand combined to operate substantially as and for the purposes shown anddescribed.

. FRANCIS O. CLARK.
